Title: Rear light correction device
Inventor: KONDOU NORIAKI
IPC: H04N5/243
Filed: 1989-05-26
Abstract: PURPOSE:To obtain sufficient correction effect by comparing the integration weight sum of outputs of an AGC amplifier given with an image pickup signal with a reference signal corresponding to a light area. CONSTITUTION:A circuit 26 subtracts a sum value EO for each field and an iris reference signal DIref to each other and the result is fed to an iris 3 as a control signal SIR via a digital low pass filter 31 and a D/A converter 32. A circuit 27 subtracts a sum EO for each field and an AGC amplifier reference signal DAref to each other and the result is fed to an AGC amplifier 6 as a control signal SAG via a filter 3 and a converter 34. An image pickup signal Ss at the standard state from the amplifier 6 is kept to a prescribed signal level. At the rear light correction, the iris 3 is opened larger than that at the standard state and the signal Ss whose signal level is closer to the saturation level than at the standard state is outputted from the amplifier 6 by the control of the iris 3 and the gain control of the amplifier 6. Thus, sufficient correction effect is attained.

Title: Working load monitoring device for machine tool
Inventor: TORISAWA YOSHIO
IPC: B23Q17/09
Filed: 1987-05-28
Abstract: PURPOSE:To permit the comparison with high accuracy in the finishing work by providing an amplification rate calculation part which calculates and instructs the amplification rate of an amplification part on the basis of the set threshold value or the working load signal and a threshold value calculation part which calculates the set threshold value according to the amplification rate of the amplification part. CONSTITUTION:When the set threshold value (p) or the detected working load signal (l) is small, the amplification rate (k) of an amplification part 12 is increased, and when the set threshold value (p) or the detected working load signal (l) is large, the amplification rate (k) of the amplification part 12 is reduced. The threshold value Q is calculated in a threshold value calculation part 17 according to the adjusted amplification rate (k), and the threshold value Q and the working load signal L amplified in the amplification part 12 are compared in a comparison part 14. Therefore, the comparison with high accuracy is permitted in the finishing work, needless to say in the rough working.

Title: Optical mouse
Inventor: KOIKE EIJI
IPC: G06F3/0354
Filed: 1987-05-28
Abstract: PURPOSE:To reduce the production cost of an optical mouse by using a regular reflection surface and a diffusing reflection surface to form a 1st line pattern, then using both high and low diffusion reflection surfaces relatively different in diffusion reflection factors to form a 2nd line pattern respectively. CONSTITUTION:For instance, a 1st line pattern showing a 1st direction (x-axis direction) is formed on the surface of a white paper 6 with transparent lines 7L serving as the regular reflection surfaces and the lines emerging among those lines 7L as the diffusion reflection surfaces. While a 2nd line pattern showing a 2nd direction (y-axis direction) is formed with white lines 9L in the y-axis direction serving as high diffusion reflection surfaces and black lines 10L serving as low diffusion reflection surfaces having relatively different diffusion reflection factors. In such a constitution, the function of a mouse pad is secured. In other words, the paper can be used as the base material of the mouse pad and the line patterns can be formed on the pad via a simple means like a print paper, etc. Then an optical mouse is obtained easily and at a low cost.

Title: Data reception circuit
Inventor: NAKAGAWA YOSHIHIRO
IPC: G06K15/00
Filed: 1987-05-30
Abstract: PURPOSE:To eliminate the missing of a black data such as sampling mistake of a black dot in black/white data by adding a circuit storing its black data over a time of an internal sample period width from a change point from a white data to a black data. CONSTITUTION:A black edge detection circuit 4 generates a pulse BED detecting that the reception data ID changes from a white level to a black level based on the received data ID inputted to a synchronizing circuit 3. A black data storage circuit 5, based on the signal BED, outputs a black data pulse BD having a time width corresponding to a data sample frequency and obtains an OR output between the pulse BD and a data SD from the synchronizing circuit 3 from an OR circuit 6. Every time the black edge detection circuit 4 detects a black edge, the data storage circuit 5 generates a black data storage pulse BD, and the pulse BD is reset by a black data edge detection output BDEP from a black data edge detection circuit 8. Thus, sure sampling is attained.

The distillation is continued until the acetone odor of the distillate disappears. The distillate is added with 1pt.wt. of decloroing carbon powder, and filtered to obtain colorless and transparent lactic acid. The content of lactic acid in the product is 85.2%, and the product meets with the specification of lactic acid as food additive.

Abstract: PURPOSE:To shorten the grinding time and improve work efficienty by regularly moving a grindstone wheel molded with multiple grindstones having different grain sizes in one body up and down the to the right and left with a cam rotated as a work shaft is rotated. CONSTITUTION:A work 16 is first ground with a woughing grindstone 2, thus a case 7 is pulled by a tension spring 10 and lowered, as a result the roughing grindstone 2 hits the work 16 and grinds it, and as the grinding proceeds, a shift cam 12 is rotated to act on a cam follower 11, and the case 7 is pressed to the left against the tension spring 9. Thereby, the grinding partition of the roughing grindstone 2 is moved to the right, and when it reaches the boundary with a finishing grindstone 3, a notched cam 14 presses a cam follower 13 upward and allows a grindstone wheel 1 to escape from the work 16. During that time, the finishing grindstone 3 reaches above the work 16, the notched can 14 finishes its escape action, the finishing grindstone 3 is pressed to the work 16 to perform finishing grinding.

Filed: 1988-06-02
Abstract: PURPOSE: To obtain nonvolatile characteristic and also to enable writing and reading circuit data at a high speed and with high reliability by using ferroelectric capacitor which selectively stores two polarization states as a nonvolatile memory element of an electronic memory. CONSTITUTION: A memory circuit 20 has a ferroelectric capacitor 22 and access transistor Tr24. The capacitor 22 can be set so as to have a negative polarization state of data 1 shown by the downward arrow, and also to have a state of data 0 shown by the upward arrow. When a signal is in a high state with a word line 28, Tr24 connects the capacitor 22 in series across a line 26 and a line 30 by becoming on-state. Then, the line 26 becomes a positive voltage from zero. Also, the polarization of the capacitor 22 is shifted from a point P(1) to Ps. When the voltage of the line 20 drops, the polarization returns to point P(0). Namely, there is an effective current shift to the line 30 via Tr24.
